Abstract
The waveguide includes an input section and a short circuit section which each have a hollow interior of like size and shape enclosed by a surrounding wall. In arrangement, the input and short circuit section are in spaced alignment, and the stripline is interposed in the gap between the two sections. The stripline includes ground planes on either side thereof, and apertures are cut into the ground planes of the same size and shape as the hollow interiors, and, in arrangement, the apertures are in alignment with these hollow interiors. A wall of pins is disposed between the two sections whereby to simulate the continuation of the waveguide walls. The position of the transition may be arbitrarily chosen to suit the design of the stripline circuit.
